UI: Remove OpenGL Render operators from Render menu

Rendering OpenGL/Preview is accessible from each editor.
Render settings are accessible from the Film menu when in OpenGL/Preview engine.
It wasn't always predictable especially with Workspaces without or with many viewports.

Also reordering of items, renaming and removal of superfluous icons.

Cleanup: warnings, trailing space

Cycles: Raised thread stack size to 1MB for macOS to be consistent with Windows.

Embree BVH builds would run out of stack space in the default of 512kB.
This means macOS builds have to stay with pthreads and can't use std::thread.

Cycles: Updated Embree integration to version 3.2

GPUMaterial: Normal Map Node: Make default inputs interactives

GPUMaterial: Fix assert when shader failed to compile.

GPUMaterial: Make Mapping node use UBO storage

This means tweaking parameter is now interactive and does not need to
recompile the shaders.

GPUMaterial: Make Localize tree live longer

This is in order to reference the localized node->storage when populating
the UBO data.

GPUMaterial: Fix nearest sampling

texelFetch return vec4(0.0) if the target pixel is outside the texture
rect. So we mimic the default repeate mode that we have for linear
interpolation.

Fix T56156 Mapping-Node doesn't work

GPUUniformBuffer: Fix bad memcpy error catched by asan

We need to copy the size of the gputype not the padded type.

Remove mode handling

Fix T56197: Cycles OpenCL build error after recent changes.

Subsurf: Evaluate all UV layers

Before that it was only first UV layer which was properly evaluated,
the rest were ignored. Now all layers are being properly handled.

Subsurf: Add API to provide vertex sharpness

Currently unused, added for the future and API completeness.

Subsurf: Support subdivision of mesh with just loose elements

Subsurf: Cleanup, remove unused mappings and topology queries

Subsurf: Fix/workaround crashes and failures with non-manifold geometry

The idea is simple: do not provide full topology to OpenSubdiv, leave
edges creation to OpenSubdiv itself. This solves issues with non-manifold
meshes which were known to fail, including the ones from T52059.

On a positive side we can simplify our side of converter, keeping code
shorter.

it is still possible that we'll need to ensure all loops has same
winding, but that is less things to worry about.

Subsurf: Use edge sharpness directly from converter

Seems it's behaving correct now, surely more tests needed, but
this is required for now to move forward.

Subsurf: Support subdivision of loose elements

Applies to vertices and edges. Biggest annoyance here is that OpenSubdiv's
topology converter expects that there is no loose geometry, otherwise it
is getting confused.

For now solution is to create some sort of mapping from real Mesh vertex
and edge index to a non-loose-index. Now the annoying part is that this
is an extra step to calculate before we can compare topology, meaning FPS
will not be as great as if we knew for sure that topology didn't change.

Loose edges subdivision is different from what it used to be with old
subdivision code, but probably nice feature now is that endpoints of loose
edges are stay at the coarse vertex locations. This allows to have things
like plane with hair strands, without need to duplicate edge vertices at
endpoints.

All this required some re-work of topology refiner creation, which is now
only passing edges and vertices which are adjacent to face. This is how
topology refiner is supposed to be used, and this is how its validator
also works. Vertices which are adjacent to loose edges are marked as
infinite sharp. This seems to be good-enough approximation for now. In the
future we might tweaks things a bit and push such vertices in average
direction of loose edges, to match old subdivision code closer.

Fix mistake in atomic bitmap

Internally values are stored as 32bit integers, no idea why i thought
they were 8 bit.
